Cockroaches appear to be suitable mechanical transmitters for a wide range of food borne pathogenic microorganisms due to their habit of feeding on excreta or garbage and occurrence in places where food is stored or handled. Therefore, they can play a significant role in the dissemination of...

Forests play a crucial role in order to maintain terrestrial ecological diversity. In this study, two distinct forest types—built environments (Forest Reserve 27) and regenerated forests (Lusaka National Park)—in Lusaka, Zambia, are compared with respect to their bird species diversity and...

A quantitative cross-sectional study was conducted to detect the presence of E. coli in unprotected water wells of Chaona community in Mwachisompola area, Chibombo District. A total of 48 wells drawn from four villages were sampled from the study area and an exposure assessment was done by use of...

Human exposure to Lead (Pb) through the ingestion of contaminated groundwater with Pb has been associated with countless health effects. The current study aimed to determine the Pb levels in groundwater and assess the associated human health risks of exposure to Pb through the consumption of...

Lead (Pb) contamination in the vicinity of lead mines and smelters affects both humans and animals. Chronic exposure to Pb via dietary intake of animal products such as milk from contaminated areas poses a health risk to consumers. Therefore, the aim of the current study was to evaluate the human...

Mining is one of the main sources of heavy metals that present great harm to human health even in low concentrations. Lead (Pb) contamination of food and especially of frequently consumed vegetables is a growing public health concern worldwide. Although levels of exposure in developed countries...

A lot of research in ecotoxicology is currently focused on identifying and developing suitable biomarkers for use in assessing environmental pollution. Thus this study was aimed at assessing the potential of Cytochrome P450 1A1 (CYP 1A1), Cytochrome P450 3A (CYP 3A) and Metallothionein1 (MT 1) as...

Studies were carried out in the South Luangwa National Park, located in the Luangwa Valley Zambia., on the behaviour, ecology and vectorial capacity of G. brevipalpis and G. m. morsitans and G. pallidipes. The catch of G. brevipalpis was low in odour baited epsilon, NGU2G, F3 and biconical traps...
